Description

12V Underfloor Heating Thermostat 2 outputs incl. mounting frame. Can be used used for our 12V underfloor heating system but with 2 zones could also be used for other purposes. It is a two-sensor thermostat designed to control temperature in heating and cooling systems. The device consists of two regulators enclosed in a common housing. Control inputs and outputs can operate in heating or cooling mode. Thanks to the use of mathematical functions, the measurement from one or the other sensor (or two at the same time) can be calculated in the form of a difference or an average. The controller has a digital temperature display and measured value adjustment function. The accuracy of the temperature control (hysteresis) is adjustable between 0.1 – 20.0C. The controller has a maximum switching capacity of 16A per zone. The operating mode “heating” or “cooling” can be set via the menu.

Temperature reading on the controller
The  regulator has a digital temperature readout and the ability to calibrate the readings. The value from both sensors is displayed alternately every three seconds. The user can set the regulator to display a single reading. The built-in siren has been designed in such a way that it provides acoustic information about the activation of outputs and alarm states.
Two-channel controllers maintain the object temperature with hysteresis set in the range of 0.1 to 20.0°C. Uses can include Independent control system for two heaters and a control system for two heaters with two temperature settings. As the device uses 2 16A relays as opposed to one 20A relay it can also handle a higher load this allowing more heating power if required with also the option of multiple zones.
